Firstly, I am not an expert in QM, so you should take everything I say with a whole serving of salt.
1) Yes, counterfactual = contrafactual. What other interpretations of QM say about counterfactual definiteness I don’t know. But wikipedia seems to give at least a cursory understanding to what is necessary for any interpretation to QM.
2) You could understand it that way, yes. Basically, the existence of hidden variables means ‘just’ that our current theory of QM is incomplete. So basically there is no collapsing wave function or decoherence or anything and all the seeming randomness we observe just comes from our not knowing which values those hidden variables take.
Again, if all I have said is complete and utter nonsense, please correct me!

Also not a QM expert, but this matches my understanding as well.
